## Description

The ICUSB2322I 2-Port Industrial USB to Serial Hub with DIN Rail Clips converts a single USB port into two RS232 serial ports, enabling you to connect to, monitor and control your serial devices. Featuring rugged metal construction, with sturdy wall-mounting brackets and top-hat DIN Rail clips (included), this USB to Serial Hub provides versatile mounting options and a robust solution for both harsh industrial environments and simple desktop installations. This USB powered adapter also retains assigned serial COM port values once connected, allowing the same values to be automatically reassigned to the ports provided by the adapter. Backed by a StarTech..

Review: Industrial quality, flawless operation. - Tried many cheap USB to RS-232 converters, what a waste of money and time trying to get them to work properly; nothing but communication errors and frustration. This one works flawlessly in Windows 7, 8.1 and 10; drivers installed automatically (no disk needed) and COM ports are persistent (never change) between multiple devices; it looks like the driver always remembers a serial number (or somehow is able to identify a specific unit) of the device and assigns it the same COM port every time this specific device is plugged in. Used 3 of those converters on the same computer without any problems whatsoever. Has an external 5V input port (I think it is a standard 2.5mm plug) but I did not need to use it; it works flawlessly getting it's power only from the USB port. The case is solid steel and comes with a DIN rail adapter as well as it can be surface mounted with screws. Love the send and receive indicator lights (for each port) since I can visually identify what is happening with either serial port. Also has a power LED. I cannot say anything about it's high speed serial performance since my application calls for only 38.4kbs and it has been running without a single error for months now. At this speed, basically saturating both ports with data traffic, it is just slightly above the ambient temperature (cannot really call it warm). As for reliability goes, I have been using approx. 15 of those converters for several months (purchased from different sources including desertcart), not a single DOA or failure. A true industrial quality USB to serial port converter that is very reasonably priced.
Review: Amazing Adapter Eliminator - This is the greatest! What an amazing device. I have fought with various adapters for years and they are always causing problems, especially when you add a new device. This box works perfectly and replaces all those irritating adapters. I have a weather station, 2 ham radios, and a communications device all plugged in and they can all be used at the same time. No issues with port numbers or anything like that. Plus, eliminating the serial/usb adapters freed up the usb ports on my PC that they were using. In addition, all the serial cables go to this box which can be located out of the way, reducing cable clutter at my PC. This is a terrific adapter hub and I highly recommend it to anyone who uses more than one serial/usb adapter.

## Questions & Answers

**Q: Does this give "true" rs232 ~12v signals on pin 2 and 3 rather than just 5v? also it says "no power outlet required" but there is a plug?! what gives?**
A: Technically the original spec has been modified many times. In 1981 when I first dealt with it, the values were 15 volts positive and negative. Thanks to the IBM PC that only had 12 volts positive and negative, many people mistakenly think that is the standard. Currently the standard will accept positive and negative 25 volts, with any signal above 3 volts or below negative 3 volts being valid (that value has not changed). I know and understand what you are asking for, a non-TTL signal level. I am ordering this myself and will let you know.

**Q: Is this taa compliant?**
A: The country of origin is Taiwan. The company does has not posted a TAA cert. It is however, RoHS compliant and FFC approved. You may contact Star Tech for further info at Tel: (800)265-1844. As a product, I recommend it very highly. Sorry I cannot answer more directly.

**Q: Can i assign coms? for example ch1 = com1 ... ch16 = com16**
A: Yes, you will be able to assign / change COM ports with the ICUSB23216FD. The ICUSB23216FD also supports COM port retention, which retains the assigned serial COM port values.

Atha, StarTech.com Support

**Q: Doesn't seem to come with the power cable. Is there a name for that type of power cable?**
A: ICUSB2322I pulls power from the USB host and does not require a power adapter. If the preference is to use a power adapter, any 5V, 0.5A (or higher) with an M barrel connector will work. Brandon, StarTech.com Support

*by D***I on March 22, 2016*

The Startech ICUSB2324I 4-port USB to serial adapter is an excellent product! The FTDI USB to serial port chips are very stable. Sturdy steel case. LEDs for each channel indicate port activity, which is handy for diagnostic purposes. And it is powered via USB port from computer, with option for external 5 Vdc power if needed. Would purchase again, and highly recommend. Also available in 2-port and 8-port versions for different size applications.
